  1. HECATE1 (HEC1) is a target of WUS and that it contributes to SAM function by promoting stem cell proliferation, while antagonizing niche cell activity. HEC1 represses the stem cell regulators WUS and CLAVATA3 (CLV3)
    [PMID: 24576426]
  2. HEC1 acts as a local modulator of auxin and cytokinin responses to control gynoecium development in Arabidopsis.
